Many tubes, according to dust cyclone separating principle, when centrifugal dust filter entrance into the air by contour of iron whirlwind son principle of motes in tangent entrance, the centrifugal force function was whirlwind separated by gray, door, purify air via core tube gas-collecting box. This is not only used in all kinds of boiler soot dust control and metallurgy, mining, building material, chemical and other industries to dust the ideal equipment for the quality.

This filter structure reasonable, wear resistance and long service life, cover an area of an area small, low operating cost, convenient maintenance and management, is a kind of novel structure, high efficiency and energy saving new filter.
